If there's no defined callout for the specified launch point the error will be raised.

getFromLaunchPointIfExists

It's the variation of the getFromLaunchPoint (see above) method. The only difference is that there will be no error if the callout isn't founded. In that case the method simply returns null. it allows to check for the existence of the callout instance silently.

getFromCalloutDescendant

This method allows to get a callout instance from the DOM element located inside it's structure. It allows for example to get the callout from its content. The only argument is the DOM element. If the chosen DOM element is not inside the callout or the callout is not found for the some reason the error will be raised.

How to Create a Callout

There are two methods to create a callout. Both methods accept a callout creation options object and return the created callout instance. For the details of the creation see the first article of the series.

createNew

The method createNew which allows to create a callout is described in the first part of this series.

createNewIfNecessary

The method createNewIfNecessary is almost identical to the createNew but creates the callout only if there's no callout for the target launch point already. If there's a callout it will be returned instead of the creation of the new one.

var callout = CalloutManager.createNewIfNecessary(calloutOptions);

How to Remove a Callout

If you need to remove the callout you need to pass it to the remove method of the CalloutManager:

This was super helpful. Thank you so much for posting these articles! I have one question though. What is the best way to make a "tour" from these popups? For example, clicking on a page element would open one, but clicking on an option within the callout should close that callout and open the next one. How could we do that? Creating the callout ahead of time and calling open() doesn't appear to work. :(

Hi Sunira! Before I will try to help you to implement such a functionality check this library: http://usablica.github.io/intro.js/ (click the green button on the page for quick demo). I think it's a better alternative for your scenario.

I have a custom aspx page in which i want to replicate the callout out of box feature of document library with all the footer link,, I searched in net a lot and didn't get any solution.. could you help me please.. Thanks in advance..

It's not obvious what do you mean by "current". This article is about using the callout framework in general, to show any information regardless of context. So here we are talking not about the callouts which are raised by SP when you are clicking on some list items for example.

Hi Alex, I want to edit URL of Compliance Details of document library item. Do you know how to do it by using callout framework? I took a look into calloutCreateAjaxMenu, CalloutActionMenuEntry but no idea how to get it or override it. It would be much appreciated if you can help.

Hi Patrick! Sorry but unfortunately I've lost my interest in SP development now and I've already fogot a lot. Anyway I've done only a little research on the subject of callouts framework so I don't know the answer to your question. :(
